I'm super out of touch with standard but always a fan of competitive brew and if you are beating tier decks with 20 copies of Hare Apparent all I can say is that's epic

So far I have won 80% in standard play. Creature removal doesn't seem to slow it down that much. Multiple board wipes are really what kills it. Actually it's doing quite well and is not that expensive on arena. I am finding two ways to play it: 1. Build up all your mana and cast a ton of rabbits at once. Green splash could help this but I feel like it also may cost picking a ton of rabbits. 2. Cast the rabbits as fast as you can but don't kill them off as fodder. Hold off a few turns and either have a banner of kinship and drop it then kill them in 1-2 turns or if you don't have a banner then you have to brute force it. However, I am managing to draw a banner pretty regularly.

Anyway, enjoy!

This deck looks so fun!!!! Alas I don't play Arena and cannot justify the expense to assemble it in paper ;(

Raise the Past seems like a decent spell here.
